THOMAS BRIGHT, OF MARENGO, ILLINOIS.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 226,030, dated March 30, 1880.

Application filed February 12, 1880.

To all whom zt may concern:

Be it known that I, THoMAs BRIGHT, of Marengo, in the county of McHenry, and iu the State of Illinois, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description thereof, rei"- erenee being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in certain improvements in the construction of windmills, as will be hereinafter more fully set forth, and pointed out in the claim.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation of a windmill embodying my invention. Fig. 2 is a central vertical section of the same.

A represents the tower of the windmill, constructed in any suitable manner for the purpose, and provided at the top with a cap or plate, B.

C is the tail-casting, or the casting to which the vane is attached. This casting is cast on a tube or piece of gas-pipe, D, in such a manner that the tube will project a suitable distance above that part ofthe casting.

The tube D is passed down through the top of the tower and through a collar or bearin g, E, which is adjusted in proper position by means of set-screws a a, passing through the legs of the tower.

Over the upper end ot the tube D is passed a box, F, which is chilled as hard as possible, and in this box are placed a number of beveled rollers, b I), as shown. The box and rollers are then covered by a chilled cap, G, which sits and turns on the rollers.

H is the main casting, which carries the wind-wheel. This is also cast on a piece of gas pipe or tube, I, of such length as to pass through the cap G and box F and iit into the tube D. The parts are so arranged that the main casting H will rest on the cap G.

I am fully aware that rollers have been used in windmills; but in such cases the rollers have been arranged in the main part of the mill, causing wear, which soon injures the mill. In my case the rollers are placed in a hard chilled box entirely separate from the castings of the mill, and a chilled cap placed on top of the rollers, on which the main casting rests. There can, therefore, be no wear from the rollers on the castings, and it' at any time the box or cap should wear they can easily be replaced without much expense.

To a stud 011 the casting O is pivoted the weighted lever J, having a short arm, d, projectin g above the pivot-stud.

On the hub of the main casting H is an eye,

i, and this eye is connected with the arm d of the weighted lever by means of a rod, It, having a h ook at each end, as shown, to take into said parts and be fastened by pins or keys.

This forms a simple, cheap, and durable con,.'

neet-ion, which acts positively and is not liable to get out of order.

A vane of any suitable construction is to be attached to the cast-ing C for turning the wheel according to the direction of the wind. The weighted lever J, by its connection with the casting H, holds the wheel more or less in the wind, according to the force of the wind, and by adjusting the weight on the lever greater or less force of wind will be required to turn the wheel out of the wind, and as the wind lulls the weighted lever brings the wheel back into the wind again.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the casting O, with tube D projecting above the same, the main casting H, with tube I, and the interposed chilled box F, with rollers I) and chilled cap G, substantially as and for the purposes herein set forth.

In testimony that Iclaim the foregoing Ihave hereunto set my hand this 23d day ot' Janu- Witnesses:
